The healthcare team also considers the type of Wilms tumour when they plan treatments.

Treatment for stage 2 Wilms tumour with anaplastic (unfavourable) histology involves surgery to remove the cancer, followed by radiation therapy to the abdomen and chemotherapy.

Surgery

Surgery is the main treatment for stage 2 Wilms tumour. It is followed by radiation therapy or chemotherapy or both, depending on tumour histology. The most common surgery used is a radical nephrectomy (removal of the kidney) with lymph node removal.

Chemotherapy

Chemotherapy is given after surgery for stage 2 Wilms tumour. For tumours with anaplastic histology, chemotherapy is given after radiation therapy to the abdomen. The type of chemotherapy most commonly used is based on the type of tumour.

Favourable histology tumours are treated with vincristine (Oncovin) and dactinomycin (Cosmegen, actinomycin-D). Chemotherapy is given for 19 weeks after surgery.

Favourable histology tumours with some chromosome changes may be treated with vincristine, dactinomycin and doxorubicin (Adriamycin) for 25 weeks.

Focal anaplastic tumours are treated with vincristine, doxorubicin and dactinomycin. These drugs are given for 25 weeks after surgery and radiation therapy.
